DISCHARGE-NOZZLE AND CONTROLLING MEANS THEREFOR.

Specification of Letters Patent.

Patented. Jan. 2, 1917.

Application filed June 8, 1915. Serial No. 32,941.

1 structure which when closing will shut off the inflow of water into the tank without the hammering or noise which is present in the devices now generallyin use.

While the present invention is illustrated in connection with the inlet of flushing tanks, it is to be understood that the same is equally as well adapted for use in all structures where the stream flow is desired to be controlled or diffused.

The invention consists primarily in the employment of a diifuser in the discharge orifice which vwill break up or difluse the stream issuing from the end of the nozzleand to provide a valve for controlling the stream flow and which seats on the peripheral edge of the nozzle, the stream flow striking the face of said valve at an angle when the valve is unseated.

Vith the'above mentioned and other objects in view the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction within the scope of the claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

To more fully comprehend the invention, reference should be hadto the accompanying sheet of drawings wherein Figure 1 is a view of a closetflushing tank, disclosing the water inlet and outlet, the ball operated inlet valve and the mechanism' for controlling the outlet valve. Fig. 2 is a sectional view of the water inlet disclosing my improved inlet valve and the diffusing means in the inlet nozzle.

Referringmore particularly to the drawings, wherein like characters of reference designate corresponding parts throughout the several views,1 indicates a suitable flushing tank provided with the usual cover 2. A water inlet pipe 3 extends upwardly through the bottom of the tank and carries at its upper end a contracted outlet or nozzle 4 having an outwardly beveled wall 4. The nozzle is surrounded by a casing 5 which rests on an annular flange 6 and is secured thereto by the screws 6. A spider i is mounted in the discharge nozzle 4:, and the same receives the shank 4 of a bafiie or diffuser which is positioned centrally within the discharge nozzle and carries at its end an enlarged head i having a flat underface 4". The head 4 of the diffuser is in a'plane slightly below the edges of the discharge orifice of the nozzle so that the stream issuing from the nozzle will be deflected and strike the surface of the hereinafter described valve at an angle. Extending vertically through the casing is a valve stem 7 carrying at its lower end a plate 8, to the peripheral edge of which is threaded the upper portion of the ring 9, which is formed with an inwardly projecting annular flange 10, having an outwardly beveled annular inner lower wall 11. A packing 12 preferably of leather is held between the flange 10 and the lower surface of the plate 8, and said packing is adapted to rest on and close the contracted discharge nozzle of the inlet pipe. By pro viding the valve with the outwardly and downwardly beveled annular wall 11, the,

water issuing from the nozzle 4: in an inverted conical stream, owing to the action of the diffuser thereon, will strike the packing 12 at anangle, and as the valve is opening or closing,.will be deflected radially from the nozzle, and the force thereof against the valve will be dissipated angularly from the nozzle, and will not be forced back onto the on-fiowing stream which causes the valve to pound when closing.

The casing 5 is formed adjacent its lower end with an opening 13 into which is threaded one end of 1a filler pipe 16 leading into the tank.

A flushing pipe 17 leading to the closet bowl also communicates with and opens at its upper end into the bottom of the tank 1, and said pipe is controlled in the usual manner by the ball valve 18 carrying a stem 19, which cooperates with a member 20 connected to a pivoted crank arm 21 operated by the pivoted handle 22.

A bowl filling connection 23 leads from the casing 5 into a larger pipe 2A which operates in a slot 32 in the valve stem By providing the diffuser with a head having a flat under surface, the column of water passing through the nozzle will strike the flat under-surface of the head and will be directed thereby against the inner periphery of the nozzle and will issue therefrom in the form of an inverted cone.

It is tobe understood that my improved diffuser may be applied to any suitable form of nozzle and to types of structures wherein there is employed a type of valve which when closing the discharge orifice of the nozzle fits over the end thereof.

Having thus described my invention what I claim and desire to protect by Letters Patent is I 1. A water inlet for flushing tanks or the like, consisting of an inlet pipe extended withinthe tank and connected to asource of supply under pressure, a nozzle on the discharge end of said pipe provided with a discharge orifice having an outwardly beveled interior end wall, a valve of greater diameter than the discharge orifice of said nozzle, and adapted to seat thereover to close the same, means for mounting said valve, a packing carried by said valve for contacting with the discharge end "of said nozzle, a downwardly extending annular wall surrounding said packing and formed with an outwardly and downwardly beveled interior surface for directing the issuing stream, externally of the sides'of said dis charge opening, a diffuser in the outlet ori- Gopies of this patent may be obtained for fice of said nozzle for( breaking the stream issuing therefrom and cooperating with the beveled wall of the discharge orificefor directing a portion of the same against the beveled surface of said ring, and means for raising and lowering said valve relative to the discharge end of said pipe;

2, A valve structure of the class described, comprising a discharge nozzle having an inwardly beveled wall surrounding the outlet orifice therein, a valve for fitting over and closing the discharge end-thereof and of a diameter to extend, beyond the edgesof the discharge nozzle, and means carried by the nozzle within the path of the issuing stream and cooperating with said beveled wall for-directing the stream flow issuing from said nozzle onto said valve at an angle to the face thereof.

3. A valve structure of the class described, comprising a discharge nozzle, a diffuser within said nozzle comprising a shank positioned centrally of said nozzle and having at its outer end an enlarged'head lyingin substantially the same plane with'the surface of the discharge end of the nozzle, and a valve for fitting over the end of the discharge nozzle and of a diameter larger than the nozzle for controlling the stream issuing therefrom.

l. A valve structure of the class de-' scribed, comprising a discharge nozzle hav ing an outwardly flared discharge orifice, a diffuser within said nozzle comprising a shank removably positioned centrally of said nozzle and provided at its outer end name to this specification in the presence of j two subscribing witnesses.
